Labosir Quest

Labosir Quest is your personal dojo for mastering two of the world's most important tactile and audio alphabets: Grade-1 Braille and International Morse Code. Whether you are learning Braille to read by touch or Morse Code to communicate without sight, Labosir Quest guides you from your first letter to black-belt fluency — entirely offline, no account required. Train with purpose. Every session is shaped by a dual adaptive engine that pairs the classic Leitner spaced-repetition system with a confusion matrix that tracks exactly which glyphs you mix up and brings confusable pairs back together until you can tell them apart without hesitation. New glyphs unlock in proven batches — Braille in four alphabetic groups, Morse in six Koch-sequence sets — and the next batch opens only when you have earned it. Feel the difference. Braille drills use a purpose-built six-dot cell tapper that mirrors a real Perkins-style key arrangement. Morse drills use a telegraph key pad with live timing: hold for a dash, tap for a dot, and hear every signal through a synthesized 600 Hz sidetone — just like a real operator's setup. A signal lamp blinks in sync so you can train by eye and ear together. The built-in Transcriber converts any text to its Braille cell rendering and Morse string instantly, and you can save favourite phrases for targeted phrase-mode drilling. Track your climb. Belt ranks from White to Black mark your mastery per script, earned as your cards advance through the Leitner ladder. After every session a report card grades your performance, shows your speed on a precision dial, and surfaces newly discovered confusion pairs. The Insights tab displays an interactive confusion heatmap, accuracy and pace charts over time, and a full Leitner box breakdown — so you always know exactly where to focus next.
